BRAKE-APPLYING DEVICE.

Application filed March 24, 1926.

The object of this invention is to provide means for applying theemergency brakes of a train if some of the wheels thereof should leavethe rails so as to quickly bring the train to a stop and thereby preventaccidents.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing our invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an elevation of a portion of a railway car showing the invention inuse.

Figure 2 is an enlarged detail view of a part of the appliance.

Figure 3 is a section on line 3-3 of Figure 2.

Figures 4t and 5 are views showing a modification.

In Figure 1, we place a drain cock 1 in the air line A. of each car ofthe train and attached to the handle of this cock is a cable 2. Thiscable is attached to an arm 3 on a rock shaft l. which is carried by abracket 3 depending from the car body. A second arm 6 on the rock shafthas fastened thereto a cable 7 which is attached to a journal box 8 onthe truck of the car. lVe prefer to attach the cables to the arms bymeans of U-bolts 9, the arms being grooved, as at 10, to receiveportions of the cables.

Instead of using cables, we may use rods, such as shown at 11 in Figures4 and 5, these rods being connected to the arms 5 of the rock shafts lwhich also carry the arms 6 which are connected with portions of thetruck by the cables 7. These figures also show each arm 6 as formed withthe pin carrying projection 12, the pin 13 of which will engage the arm5 when the arm 6' is pulled downwardly by the cable 7, due to the wheelsleaving the tracks.

Serial No. 97,081.

As will be seen from Figure 1, the journal of each wheel may beconnected with the device. If one or more wheels should jump the track,the wheel, as it leaves the track, will move its journals downwardly sothat the cable 7 would be pulled upon, so that the rock shaft to whichthe cable is attached would be rocked, and this movement will becommunicated to the cable 2 or the rods 11 through the connections shownand this movement of the cable 2 or rods 11 would be communicated to thehandle of the cock so that the cock will be opened and the air linedrained to apply the brakes. Thus the train would come to a stop shortlyafter the wheel left the rail and thus wrecking of the train would beprevented.

It is thought from the foregoing description that the advantages andnovel features of our invention will be readily apparent.

We desire it to be understood that we may make changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall Within the scope of the appendedclaim.

lVhat we claim is Incombination with a railroad car and its air line, acock for draining the line, brackets depending from the body of the car,a rock shaft supported at the lower end of each bracket, a pair ofdivergently arranged arms on each rook shaft, laterally disposed headportions on each arm formed with longitudinal grooves, a flexibleelement disposed within the groove of one arm, a U- bolt locking saidflexible element in position and having connect-ion with the handle ofthe cock, and flexible means attached to the head of the other arm andhaving connection with a part of the journal of an axle of the tire sothat when the wheels leave the track the cock will be open to apply thebrakes.

In testimony whereof we af'iix our signa tures.
